    GPR injectors or pink 565cc inj for stage 3 SHO

    Hello

    Now I have gpr inj and I have some problems at idle and between 5k to 6k rpm, the power it varies. I wonder if is better to use pink injectors. Any advice?
    Thx.
    Sergiu

    Need to tune for the injectors in the ECU you can run 1000cc injectors if you compinsate in fuel table... idle is vacuum so that would be the lowest table it should run 12.8-13 idle I would think

    Your conditions are different than the tune was created in probably you need to learn the program.....get with riva tech he can probably help you understand the program and where to go to adjust it

    Well Joey I did that, I just tuned the stage 3 map with 10% more fuel but no difference, with stock inj, now after I installed gpr inj
    I have 11.4 at wot but idle is bad so I have to do the idle procedure from Riva.The question was if pink inj are better than gpr inj.

    55 psi of fuel, stock plugs, afr is 11.5 to 11.8 at wot, but at idle I have 14.5 to 15, in rest is 12.5 to 13.7.
    Today I mod BFUEL from 1000 to 6000 rpm is +10% more fuel and from 7000 to 8400rpm is -10% less.
    Air temp is about 24 celsius and water temp 18 celsius.

    You have all the parts installed for a Riva Stage 3? Are you running the Stage 3 map? If yes, the Stage 3 parts includes 100lb injectors. The Stage 3 map is based using these injectors.

    Hi bamf,

    only stage 3+ needs 1000cc inj, stage 3 needs stock inj as they say, but if you use stock inj, you go lean. Mr. Brian from Riva told me what to do but is no use, I am lean.
